I was updating my 4s to the latest software IOS 7 and unfortunately my phone fell off my desk and disconnected during the process. Now its stuck in recovery mode and everytime i connect it to my laptop it does not recognise the device. even before that my iphone wouldn’t sink due to error 29. I was wondering whether i could buy a new cpu and install it into my phone?

Hi, Easy fix :

  1. Download : Recboot, It will get exit recovery mode. 2.Error 29 is a hardware problem, Mostly replacing battery or repair in the slot of where u insert battery inside iPhone :) How do i know : I have similar issue, but my iPhone is stuck with apple loop :) Regards, kksilvery

Dec 22, 2020. Same problem. I bought a iPhone 4s 3 months ago. I bought it to play music and for wifi. It was great!!!! But, I kept ignoring the notification that asked me to update to 9.3.6 or something like that. I laughed at that and ignored it. All was well. Until yesterday. An app I very much wanted said I needed to upgrade my phone. So I hit the upgrade button and BIG MISTAKE! The iPhone 4s went into revovery mode and asked me to connect to a mac or pc with itunes. I did and it failed on Error 29 six times in a row. Online search suggested that if I had a non-iphone battery then error 29 would kill the phone and make it a brick…. so sad…. but I found an old used iphone 4s Apple battery and installed it. Then connected to itunes and went through recovery 7 times, each time failing but they said online not to give up. I got the little progress white line to move to right a little further each time. Finally, I got my iPhone back to normal.
